First off, thank you for this information! I'm trying my best to understand how this works and I do have a working setup. however, I think I'm running and extra Moca Adapter for no reason. I've made a chart to show my setup, and what I THINK i can make my setup to eliminate one of the adapters. However, my goal is not to have the Tivo use moca for its connection, but to make my router speak to my Ethernet HUB upstairs via moca.

Note: My cable modem, router and my Tivo Premier are right next to each other.

The Premiere XL4 has an integrated MoCA to ethernet bridge. Simply connect the XL4 via Ethernet and enable MoCA + Ethernet in the settings. All other devices on your network that want to use the MoCA connection will have it supplied via this bridge. There is no need for adapters on any other device with an integrated MoCA client (like the TiVo Mini for example).

Wouldn't I still need an adapter upstairs to "bridge" my hub to my wireless router? There is no Ethernet connection between the wireless router and the hub, and the upstairs tivo is an old TivoHD.

Is your plan to replace the "old TiVo" with a Mini?

The thing I think you are missing is that the XL4 serves the function of bridging the MoCA to the ENTIRE rest of your network. As long as the XL4 has ethernet and that ethernet connection is viable across the network then any device with MoCA that connects via Coax will connect via the XL4s MoCA bridge and that device will have access to every part of your network that the XL4 does (this extends of course to the internet).

Looking again at your diagram I see the source of the confusion. You simply have no ethernet at all at the upstairs location and are using MoCA there to extend the network.

If you can't run an ethernet cable to the upstairs location, then the Actiontec adapter should get its connection via the XL4, which will have an ethernet/internet connection to the primary network. You will only need the one MoCA adapter in the network.

Thanks! Thats what I was hoping! I'm going to redo to the new setup this weekend (I'm also replacing the premier with a Roamio Plus and the old tivo with a Mini, which I realize will change the setup a bit upstairs too. but at least I now know how to do it).

So I attempted to use my new Roamio Plus as the Moca bridge, but every-time I enabled it, my downstream would go from -3.5 to -10 or and my cable modem would lose its lock and my internet would go out.

Any thoughts on why this would be? See the diagram I posted a few posts up, and look at the bottom one to see the setup that this is not happening on.

If I use a moca adapter BEFORE the 3 way splitter, I have no signal strength issues. Its when i take the adapter out, and use the roamio as the moca bridge, that i can no longer get internet.

Thanks.

Some cable modems have filters to block MoCA signals. My Motorola SurfBoard SB6141 has such a filter.

You could try manually configuring the MoCA setup with a different channel to see if that helps.

Using MoCA setup option #2 for your P4/XL4/Roamio Plus/Roamio Pro? Connect your Smart TV, Blu-ray player, Roku, game console, or other device to the Tivo's Ethernet port! Those devices can be daisy chained off your Tivo's MoCA connection. (If you want to connect multiple devices, you can get a cheap Ethernet hub and plug it into the Tivo's port too.)

If there are ideas or things missed in the guide (but remember it's not a complete and total MoCA FAQ, just a setup guide) then post them here. I'll add them!

Can a device be plugged into the Tivo Mini ethernet port and daisy chain off of the MoCA network? Thanks!

While Iw as at it I verified that using the old 1000MHz (1GHz) splitter WILL NOT WORK with the MoCA signal.

Until I changed out my 1000MHz splitter with one rated to 2400MHz, I could not get the mini to keep a connection. I hadn't thought to do this earlier as I had read over and over that 1000MHz was good enough. Yes, it could have been a bad splitter but it was only 3 yrs. old and originally installed by Comcast (decent quality I would hope) so it hadn't given me any problems otherwise with my cable modem or picture quality.

My MoCA worked with my 1Gb splitters but after setting up the MoCA system I did changed out all the splitters to ones over 1Gb, just to be on the safe side.

I have a Roamio Plus connected to directly to a comcast cable modem with no router. I have two Mini's connected and MOCA enabled but I can not get them to connect. I have a POE filer on the input side of a 3 way splitter (5-1000 supplied by Comcast). Ahead of that on the drop I have a 2 way splitter feeding another cable modem that feeds my home server and wireless network. I have two separate networks in the home and two cable modems as one is a dedicated IP feeding my server.

1. When setting up the Minis's I have tried entering the TCP/IP info that the roamio is displaying. It is connecting to the internet with no difficulties through the cable modem attached to it. When I do this, do I give the mini a different IP address or the same?
Or is this the best way to do this?

2. Both Mini's are activated with Tivo and Have been rebooted. I have forced the Roamio reconnection several times

You don't need to enter any IP addresses to setup Moca. Just connect the Minis and the Roamio to the same coax network and they will find each other. It sounds like you are trying to connect the Minis to your network both by ethernet (to your modem) and by Moca (to the Roamio); you can't do that, it's one or the other. Also, if you have two subnets running in your house then you need to make sure that the Minis and the Roamio are all on the same subnet.

Updated the OP for a bit of clarity, accounting for Roamio changes, Roamio wifi, etc. I've also given slight preferential treatment to the Roamio/Mini since that seems to be the catalyst for most of new moca questions/threads popping up. But the info for all types of Tivos is still there.

I wanted to sum up my minor hiccups and solutions that got me up and running with my new Roamio Plus and Mini setup to hopefully save someone else from having to experience the frustration I did. These may be obvious things but took me some fiddling to figure out:

I COULD NOT get the Mini to connect to the new moca setup I am running from my Roamio until I replaced my existing Comcast-installed splitter with one that was rated to 2400 Mhz. I also installed a POE filter on the main drop. The Mini then got a connection! Great!

Then, the splitter died two days later (can happen, RMA'd from online retailer). I hooked everythig back up with replacement 2400 Mhz splitter and while I was at it, split the cable modem line from the drop ahead of the POE filter and this 2400 Mhz splitter. Again, connected just fine! Great!

Then, I noticed random errors in the Discovery Bar that no connection was present on both Roamio and therefore Mini. These would often clear up within seconds. I had read others having issues with "green switches" but mine is a netgear FS105 that is only 10/100 so I didnt know if this was the same issue. I rerouted the Roamio ethernet from this switch to the router directly (linksys WRT54G running DD-WRT) and never saw these network errors again! Great!

Then, while enjoying the Mini, I would sometimes get a complete drop out "no host found, network problem, or some such" error. Again, this apparently was temporary as going back to Tivo Central on the Mini and selecting Live TV again would work with no problem. I couldn't figure this one out and didn't find much here or online directing me to a particular solution. I eventually remembered that the Roamio's cable is ran through the surge suppression of my Belkin PureAV AP11000-10. When connecting the Roamio (replacing an Tivo HD), I just hooked the cable line in not even thinking about how it was running through the surge suppressor. Thinking that this might be interferring with the moca the Roamio is trying to send back out through this line, I removed the cable line from the surge suppressor and have not had a single hiccup since! Great!

Now, everything seems to be running smoothly. (Except for one morning a couple days ago, I turned on the Roamio and was getting no picture but audio and no response to remote. Had to pull the plug to restart and have not seen this again in the few days since. Not related to moca discussion, I know, but if anyone has seen this or can provide direction, that would be great. Could have been a fluke)

I need help, I am two weeks into this fiasco and Tivo has been unable to assist though I have talked to them at least 10 times. I had all Premiers and with the kids gone I thought what a better time to tell Comcast to stop charging me for the additional outlet drops and cable cards. So I returned all but 1 cable card and now my brand new 2013 built townhome has coax in every room but I am only looking to get my tivo Roamio working in the living room, and the mini in the master bedroom.

The Master bedroom has a levitron box in the closet in which I see two splitters, and all the cat 5e end connectors that run throughout the house. First thing I tried was running a ethernet cable directly to the Roamio and the Mini. Results were the Roamio seemed to work fine but the mini could see Tivo Central and the Roamio but it simply would not play live tv and it would not play shows even though I could see them and manipulate them and showed the V113 error for about a week.

When I connect the actiontek adaptor for Moca as suggested next to the modem I lose all internet connectivity and wireless, like the router cannot see the internet any longer. I unplug it just from power and it seems to come back, I fiddled with it for several hours and still nothing. I have cable at the Roamio and Cable at the Mini but they both cannot see a gateway.

So I thought I would try ethernet again, Same results as above so I put the Roamio and the mini right next to each other on the same switch and unplugged anything else on the network, still same result No live TV, no able to play recorded on Roamio shows everything else works and still a V113 error.

I dont know what to do or try now, I thought this would be easy but after 14 years with Tivo I want to cancel and tell comcast to bring me a PVR setup.

Hi, I'm a new forum member, but an existing TiVo user (4 Premieres in house) using Comcast bundled service.

In order to save money and upgrade functionality I'm planning on switching to a Roamio and 3 Mini's, and also create a MoCa network. I need some fundamental help on the setup/architecture of the network.

I've been reading the threads as well as going to various MoCa-related sites and I'm wanting to make sure I'm correctly understanding how this technology works and how to configure it with my house setup.

On my current coax / Comcast cabling setup:

I've identified the point-of-entry to my house (where I'll install the POE filter on the input side of the first splitter (3 way).

In tracing the cables coming out of that 3 way splitter: one coax cable runs outside the house to the back / upstairs living room, where it connects directly to my premiere XL with our primary TV. I'm planning to replace this Tivo unit with the Roamio since this is where we do most of our watching.

The other two coax cables coming out of that 3 way splitter run into the downstairs.

One connects to the Comcast modem (which connects to phone system and Ethernet/Wirelss Router (2.4 Ghz Netgear).

The second coax cable goes into another splitter which feeds my other 3 TiVo units located around the house.

I've ordered an Actiontec Ethernet to Coax Adapter and a 5-1200 MoCa enabled splitter that I was going to replace the existing downstairs splitter.

I was planning to install the Actiontec adaptor next to the Comcast Cable Modem and my Ethernet Router.

If I put the Actiontec adaptor upstream of the Comcast Modem, and connect the Ethernet cable out of the router back to the adaptor will that establish the MoCa network?

Or do I need to run another coax cable out of the adaptor and into the second splitter, replacing the current cable coming from the the Point of Entry splitter?
